The search for the perfect exhaust system for the Dodge Durango SRT is over. BORLA® gives you their take on how the Durango SRT should sound. These Cat-Back™ systems are developed with performance and sound in mind on the 392 HEMI engine. The ATAK® sound level delivers an aggressive, head-turning sound that makes the 6.4L engine roar without any drone. System contains a merge X-Pipe for increased performance and improved flow. System features 4.5″ round black chrome on T-304 stainless steel tips, but polished tips are also available. Using BORLA® Stainless Steel Polish p# 21461 is NOT recommended with these black chrome tips. They suggest cleaning the tips with hot water and a microfiber cloth. Each system is built from premium T-304 stainless steel and is mandrel bent to give you the absolute best in performance and durability. BORLA® exhaust systems are covered under their Million-Mile warranty with the following exceptions. BORLA® will warranty black coatings, tip finishes, and carbon fiber parts for one year.
